IVA Subway train - Built by Întreprinderea de Vagoane Arad (now Astra Arad), between 1978 and 1995 Units: over 250 Each unit is formed by 2 motor cars, with letters A and B. The A car has a pantograph. Axle formula: B'B' + B'B' Gauge: 1435 mm Mounted axle gauge: 1426 mm Bogie weelbase: 2200 mm Wheel diameter: 900 mm (new) / 820 mm (minimum); the weels are monoblock Weight of an empty car: 36 tonnes Transport capacity (for a car): 200 passengers (at 5 passengers per square m) / 300 passenger (at 8 pass. per sq. m) Length of the car's body: 18600 mm Lenght of the whole train, over buffers: 38000 mm Width: 3100 mm Maximum height: 3450 mm Height of the floor: 1165 mm Wheelbase of the car: 12300 mm Number of electric motors: 4 (2 on each car, each motor drives 2 axles) One-hour duration power of an electric motor: 215 kW / Continuou power of an e.m.: 185 kW One-hour duration current and rotation: 310A, 1270 rpm Transission ratio: 5.38 Max. working speed: 80 km/h - this is the max. speed of our subway network Max. constructive speed: 100 km/h Min. curve radius: 150m Max. acceleration: 1.35 m/s^2 Average deceleration: 1.20 m/s^2 Min. deceleration guaranted at max. load at emergency brake: 0.9 m/s^2 Max. noise level inside the car: 82 dB
Bogie: 2-axle, with one motor, 3 out of 4 bogies are fited with current colector for the 3rd rail Primary suspenssion: Megy rubber springs Secondary suspenssion: pneumatic Brakes: electric brake (rheostatic), indirrect pneumatic brake with disks, mecanic parking brake
Multiple operation: 2 or 3 units coupled (this mean trains formed from 4 or 6 cars)
Voltage: 750 V D.C. from 3rd rail (in yard an overhead wire can be used, but max. speed is limited at 15 km/h due to the high amperage needed)
